Question

我在MSP430FF5529上使用网络微控制器CC3100

我试图从我的Android设备向主板发送数据。微控制器的程序是从德克萨斯仪器开发的示例p2p应用程序。它应该能够接收数据。它打开TCP服务器套接字并等到连接

我在本教程Android TCP Connection Tutorial上开发了一个仅基于TCP客户端部分的android应用程序。但它没有正确连接。这是cc3100打开服务器时的功能;我放置了一些CLIwrite以查看tera术语（终端/控制台）的进度。

static _i32 BsdTcpServer(_u16 Port){

    SlSockAddrIn_t  Addr;

    SlSockAddrIn_t  LocalAddr;

_u16          idx = 0;
_u16          AddrSize = 0;
_i16          SockID = 0;
_i32          Status = 0;
_i16          newSockID = 0;
_u16          LoopCount = 0;
_u16          recvSize = 0;
CLI_Write(" [TCP Server] var declared \n\r");

for (idx=0 ; idx<BUF_SIZE ; idx++)
{
    uBuf.BsdBuf[idx] = (_u8)(idx % 10);
}
CLI_Write(" [TCP Server] exit: for (idx=0 ; idx<BUF_SIZE ; idx++) \n\r");
LocalAddr.sin_family = SL_AF_INET;
LocalAddr.sin_port = sl_Htons((_u16)Port);
LocalAddr.sin_addr.s_addr = 0;

SockID = sl_Socket(SL_AF_INET,SL_SOCK_STREAM, 0);
CLI_Write(" [TCP Server] sl_Socket \n\r");
if( SockID < 0 )
{
    CLI_Write(" [TCP Server] sockID < 0 \n\r");
    CLI_Write(" [TCP Server] Create socket Error \n\r");
    ASSERT_ON_ERROR(SockID);
}
CLI_Write(" [TCP Server] Socket created \n\r");
AddrSize = sizeof(SlSockAddrIn_t);
Status = sl_Bind(SockID, (SlSockAddr_t *)&LocalAddr, AddrSize);
if( Status < 0 )
{
    CLI_Write(" [TCP Server] status2 < 0 \n\r");
    sl_Close(SockID);
    CLI_Write(" [TCP Server] Socket address assignment Error \n\r");
    ASSERT_ON_ERROR(Status);
}
CLI_Write(" [TCP Server] socket adress ok \n\r");

Status = sl_Listen(SockID, 0);
CLI_Write(" [TCP Server] sl listen \n\r");
if( Status < 0 )
{
    CLI_Write(" [TCP Server] status1 < 0 \n\r");
    sl_Close(SockID);
    CLI_Write(" [TCP Server] Listen Error \n\r");
    ASSERT_ON_ERROR(Status);
}
CLI_Write(" [TCP Server] status > 0 \n\r");newSockID = sl_Accept(SockID, ( struct SlSockAddr_t *)&Addr,(SlSocklen_t*)&AddrSize); if( newSockID < 0 )
{
   CLI_Write(" [TCP Server] newsockID < 0 \n\r");
    sl_Close(SockID);
    CLI_Write(" [TCP Server] Accept connection Error \n\r");
    ASSERT_ON_ERROR(newSockID);
}

while (LoopCount < NO_OF_PACKETS)
{
    recvSize = BUF_SIZE;

    do
    {
        Status = sl_Recv(newSockID, &uBuf.BsdBuf[BUF_SIZE - recvSize], recvSize, 0);
        if( Status <= 0 )
        {
            CLI_Write(" [TCP Server] status < 0 \n\r");
            sl_Close(newSockID);
            sl_Close(SockID);
            CLI_Write(" [TCP Server] Data recv Error \n\r");
            ASSERT_ON_ERROR(TCP_RECV_ERROR);
        }

        recvSize -= Status;

    }while(recvSize > 0);

    LoopCount++;
}

Status = sl_Close(newSockID);
ASSERT_ON_ERROR(Status);

Status = sl_Close(SockID);
ASSERT_ON_ERROR(Status);
CLI_Write(" return function \n\r");
return SUCCESS;}

当我尝试发送字符串时，它不起作用，并且在此ligne处被阻止

        Status = sl_Recv(newSockID, &uBuf.BsdBuf[BUF_SIZE - recvSize], recvSize, 0);

示例中的应用程序应连接到右侧PORT的卡IP，但是当我尝试发送某些内容时，它不会发送任何内容。我下载了应用程序TCPclient，它发送了消息，但是在控制台上我没有看到建立的TCP连接。

使用Iperf我可以检查我的Android设备和主板之间的连接，它可以正常工作。

某人有什么建议吗？
